Compile error when using KDBindings in combination with Qt #79
Description
Hi!
I wanted to use KSBindings in a project where I also use Qt. At a certain point I needed to include kdbindings/signal.h as well as QObject. This then results in a compile error (on gcc as well as clang). As I investigated further it turned out that the order of includes matter. If KDBindings is included first, it works. If QObject is first then it doesn’t.
I was surprised and wanted to ask if this is a known limitation.
The compile error looks like the following:
[ 9%] Building CXX object CMakeFiles/workshop_episode_001.dir/src/Translator.cpp.o
